The ADTRAN NetVanta 2400 is a corporate host IPSec compliant gateway providing all the necessary components required to secure an integrated VPN solution. As a large host security gateway, the NetVanta 2400 provides several key security features such as IPSec VPN tunneling with DES or 3DES encryption, stateful inspection firewall, and IKE for user authentication supporting public/private keys or digital certificates. The NetVanta 2400 employs a stateful inspection firewall that protects an organization's network from common cyber attacks including TCP syn-flooding, IP spoofing, ICMP redirect, land attacks, ping-of-death, and IP reassembly problems. The NetVanta 2400 also encrypts the data being sent out onto the network, using either the DES (Data Encryption Standard) or 3DES encryption algorithms. Data integrity is ensured using MD5 or SHA1 as it is transported across the public infrastructure. In addition, Internet Key Exchange (IKE) can be used for user authentication supporting public/private keys or digital certificates, assuring that the proper VPN tunnel is established and that the tunnel has not been redirected or compromised. NetVanta 2400 has built-in alert and logging mechanisms for messaging and mail services. Together the NetVanta 2000 Series offers the most robust features and functions to address a wide range of enterprise VPN needs.
